Yes till 65 own occupation if you can't get your medical back you don't have to become a Walmart greeter. If you medical out at 64 and can't get your medical back it goes for another 2 years I believe. up too 5000 company payed a month before taxes you can buy up to 15000 the buy up 10000 is tax free since you already payed taxes on that. But you have to make around 300.000 on your last w2 to get the full 15K.
I believe this true someone else may know more.
